Message in the MooncakeMessage in the Mooncake

"Set 800 years ago in the Yuan dynasty, Su-Ling and her family live in a village where the Mongols have invaded and made life very difficult for them. But the villagers are smart, and a plan to revolt against the Mongols begins to form with a message tucked into the Mid-Autumn Festival mooncakes: "On the 15th day of the 8th lunar month, on the day of the full moon, commence attack at midnight." It's up to brave Su-Ling to deliver the message to her uncle without getting caught by the Mongol guards."--
